What's different about buying in New Hampshire

New Hampshire has no sales tax, period — one of the cheapest states in America to buy a car. If you live in Massachusetts and are tempted to buy in NH to skip the tax: it doesn't work, you'll pay Mass use tax at registration. For NH residents, the savings are real and immediate.

Trade-in mathYour trade-in's value is deducted from the purchase price before tax is calculated. A $15,000 trade saves you $0 in tax here — which usually makes trading in beat a private sale once you factor in the hassle.
